How to Wire a Generator Hook Up
Electrical Question: I have a gasoline generator and would like to temporary hook it up (during emergencies only)to my panel to run 110 volt circuits only.
- The generator produces 5600 watts with 8600 watts starting.
- There is a 230volt 30 amp 4-wire connection on the generator.
- I want to place the generator outside my garage. Inside my garage I have an electric hot water heater with a 220V 3 wire outlet box.
- Understanding that first all incoming power must be disconnected and all 220v circuits must be disconnected. I’d like to disconnect the hot water heater and connect the generator to the hot water heater circuit in order to back feed the panel and energize the 110v circuits on the inside panel.
- My problem is that I have 4 connections on the generator receptacle and 3 wire in the outlet box for the water heater. How can this be done? I know it sounds wacky but I think it can be done.
- We have a lot of storms including hurricanes down here and need a temporary source of electricity. Present we use extension cords but we lose too much power.
Thanks for your home generator question Rusty.
Background: Rusty, a Homeowner from New Orleans.
Application: Wiring a Generator and Transfer Switch or Generator Panel.
Skill Level: Advanced – Not Recommended for Homeowners, Best installed by a Licensed Electrician.
Tools Required: Electricians pouch of hand tools and the various power tools necessary for installing the generator and transfer switch.
Estimated Time: Depends on the type and size of the generator and transfer switch and the available access to the project area and configuring the essential electrical circuits to be placed on generator power.
Precaution: Any existing electrical wiring within the immediate area that may interfere with the installation of the transfer switch may need to be relocated if necessary. The selection of the transfer switch or generator connection or generator circuit panel will affect the over all project.
Important: Installing a generator, transfer switch or generator panel must be well thought out and installed with a permit with all work being inspected.
How to Plan for a Generator and Transfer Switch Installation
Panels and Generator Circuit Power
- It would be best to install a generator panel where all your essential 110 volt circuits are fed form.
- The generator panel can then be connected to the source power receptacle of the generator.
- If possible the generator should be installed in the same area as the electrical panel.
- Maintain the approved clearances and between the generator and building components.
- The generator area should be accessible for maintenance and servicing and during a power outage.
